Ok, I’m a bit of a noob when it comes to hardware stuff. I have a Thinkpad T490 with the 1920x1080 non-touch screen. My complaint is that I ended up with the model with only 45% NTSC. I would like to upgrade to something with 72%.
AFAICT, my screen’s model # is N140HCA-EAC. 30-pin connector. Is this - https://www.laptopscreen.com/English/model/Lenovo/FRU~01YN154/ compatible?
I already know there’s no blocks or whatever in the bios preventing an upgrade, just want to make sure I buy the right thing. Would rather not ship from China so NA sellers are good.
(btw I obtained the model of what I have now by running “edid-decode </sys/class/drm/card0-eDP-1/edid”, I’m on Linux)
Yeah as for the original screen, I can’t seem to identify the revision.

“CMN5332” doesn’t appear in any searches on laptopscreen.
What you bought though, do you think that will fit my T90?
Yes, I think so. I the T495 is - as far as I know - just the AMD version of the T490.
I think it’s ok that you can’t find the revision of your screen. Just check the different revisions on panelook. I suspect they’ll match in dimensions and connector position. I Mena, they ought to, as they are the same model number, and the revision apparently is so unimportant that it doesn’t get stated by the screen itself.
